Description

A kind of granular gas purifier exempting from blowback
Technical field
This utility model is related to a kind of granular gas purifier exempting from blowback, belongs to environmental science and technology field.
Background technology
Granular bed gas purifying device, is a kind of usual means of industry dust laden air dedusting, its use principle is housing Grain bed is provided with interior ventilation terminal, housing is respectively provided with ash-laden gas import, clean gas outlet and blowback air import, anti- Flushing air outlet.When work starts, close blowback air import and blowback air outlet, dusty gas enters from ash-laden gas import, passes through Grain bed removes dust, then draws from clean gas outlet, but after a certain period of use time, can pile up various impurity and dust, Thus affecting filter effect.At this time, it may be necessary to quit work, close ash-laden gas import and clean gas outlet, using back blowing machine, from Blowback air import blasts air, through grain bed, exports from blowback air and draws, collection so can be allowed to stay the dust quilt of grain bed Take away, reach the purpose recovering dust removing effects.Do so has two major drawbacks:First, phase poor filtration effect before filtration.With The accumulation of dust, dust filter membrane can be formed so that filter effect is more preferable in granule layer surface, now to air cleaning rate Height, and blowback can destroy dust filter membrane so that the preliminary stage dust removing effects reusing after blowback are deteriorated.Second, blowback meeting Lead to the interruption of dedusting, and operate relatively cumbersome, also resulting in device manufacturing cost increases.
For this reason, improving or researching and developing dust collection method and the equipment that can avoid and overcome drawbacks described above, it appears particularly important.
Utility model content
This utility model is for avoiding the weak point existing for above-mentioned prior art, provides a kind of gas exempting from blowback net Change device it is intended to simplify purification process, improve efficiency of dust collection.
This utility model is to solve technical problem, adopts the following technical scheme that:
A kind of granular gas purifier exempting from blowback it is characterised in that:Described depurator is horizontal type structure, including laterally The housing of setting;Have dust-laden air inlet in the left side of described housing, right side has clean gas outlet;
Vertically it is provided with some dust removing units in described housing, in each dust removing units, grain bed is installed, described The arranged on left and right sides of grain bed is separately provided for wire netting and the air distribution plate of fixing grain bed;Left side in described wire netting It is provided with dust filter membrane area;It is fixed with wire gauze in the outside in described dust filter membrane area;
The bottom of described housing has extended downwardly dust collection area, described dust collection area be located at described wire gauze just under Side.
The width in described dust filter membrane area is 5~30mm.
It is provided with the middle and upper part in described dust collection area and open for the dust collection area being spaced housing and dust collection area Close;Have sealable dust outlet in described dust collection area bottom.
The through hole that some supplied gas are passed through is provided with described air distribution plate.Air distribution plate can be arranged with monoblock type, also can root According to dust removing units, carry out subdivision setting.
Pass through baffle interval, each dust removing units is an independent cleaning system, mutually not shadow between each dust removing units Ring.
Using the method that above-mentioned gas depurator is purified to dusty gas it is:
(1) dusty gas is passed through housing from dust-laden air inlet, is purified by grain bed from left to right, dusty gas Dust filter membrane area on the left of grain bed for the middle dust piles up, and gained purification gas are drawn from clean gas outlet;
(2) with the accumulation of dust, form dust filter membrane in dust filter membrane area, described dust filter membrane can improve dedusting effect Really;
(3) when dust accumulation is to wire gauze outside beyond dust filter membrane area, the dust outside wire gauze is at itself Peel off under action of gravity, fall into dust collection area, so that the dust filter membrane on the left of grain bed is consistent with dust filter membrane sector width, So that the flow resistance of air will not increase, gas flow will not reduce it is ensured that udst separation effect;
(4) when dust accumulation highly switchs close to dust collection area in dust collection area, close dust collection area switch, Open sealable dust outlet, dust is discharged dust collection area;Then turn off sealable dust outlet, open dust Collecting region switchs;In the process, purifier need not be shut down, and proceeds gas purification, continuous work.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
(1) the drawbacks of this utility model is directed to existing granular gas purifier, devises a grain bed exempting from blowback Gas purifier, makes it peel off by dust own wt, so that the thickness of dust filter membrane is held essentially constant so that air Resistance does not increase, and gas flow does not reduce, and meets use requirement, eliminates the blowback step of existing equipment, simplifies cleaned Journey.
(2) in use, there is intact dust in dust filter membrane area to gas purifier of the present utility model all the time Filter membrane, it is to avoid the process that existing apparatus are re-formed after being removed established dust filter membrane completely by blowback again, namely Avoid the process of early stage dust filter membrane formation stages poor filtration effect, thus improve efficiency of dust collection.
(3) it is not necessary to shut down during depurator of the present utility model dust in removing dust collection area, significantly carry High equipment service efficiency is it is achieved that work continuously.
(4) the wide 5~30mm in dust filter membrane area of the present utility model is it is ensured that the thickness of dust filter membrane is suitable.
